Once per turn, you may place the Catapult in a region you occupy to conquer any region that is 1 region away (but not adjacent) at 1 less token than usual. The Catapult may be used to attack a region beyond the Lake, but not over Seas. The region with the Catapult is immune to enemy conquests as well as their racial and special powers. The Catapult disappears when you go into Decline.
